Yes, everything you see in the lot is a vendor booth with the exception of the left most triangle. The entire building is full. Several RC vendors with cross-over products attend this event.
I had a ball here one year ago. Not exactly modeling, however, it’s a tinker’s delight. You need to attend this event once in your lifetime. Lots of radio, computer, antenna and misc here. You can see it in one day if you keep those feet moving fast all day.
